IBEATER FOR HOG-SCRAPING MACHINES.

Specification of Letters Patent.

Patented July 26, 1910.

To all whom it may concern:

Be it known that I, WALTER Gnssrusno- VEN, a citizen of the UnitedStates, residmg at Chicago, in the county of Cook and State of Illinois,have invented new and useful Improvements in Beaters for Hog-ScrapingMachines, of which the following is a full, clear, and exactdescription.

My invention relates to machines for antomatically scraping and cleaninghogs wherein the carcass of the animal is conveyed past one or more rowsof rapidly revolving beaters having metal scraplng blades mounted ontheir unsecured ends.

Considerabledifliculty has been found in obtaining a beater strap thatwill not form a set at the point of bend owing to the curvature itusually takes during its operation. It has been ascertained that abeater strap that can be caused to return to its original shape, thatis, to straighten out fiat when not in operation will successfullyaccomplish the purpose long sought after by machinists and othersemployed in this particular line of manufacture. These beater strapsusually comprise rubber interposed surrounding a plurality of layers ofcanvas, duck, or other coarsely woven fabriqand vulcanized. Thus, whenthe rubber strap has once taken on its set it must be discarded for, anew one. This becomes an item of considerable expense with packers andslaughter-houses where meat is dressed for the market.

It is the object of my invention to overcome this disadvantage byconstructin a beater strap that will not crease or set at its point ofgreatest curvature and which, after striking the carcass, will assume anormally straight position. I accomplish this by disposing a soft rubbercushion between the secured end of the strap and its mounting bracket onthe shaft or pulley and which I have fully described in the fol owingspec-v ification and more particularly pointed out p in the claims.

In the drawings :-Figure l is a vertical front elevation on one of myimproved beater straps showing the same mounted on its shaft. Fig. 2 isan edge view thereof partly in section, on the line-22, Fig. 1.

ig. 3 is a similar view of a slightly modified construction showing thesame attached to a spacing bracket. I

Referring to the drawings, A represents this particular point.

a suitable rotatable shaft, that preferably extends the length of themachine and to 'which a plurality of beater straps B are usuallyattached. These beater straps B preferably comprise an elongated stripof narrow composite rubber fabric (that is, layers of canvas, duck andthe like, interposed between and surrounded by layers of rubber) and tothe outer unsecured ends of which metal scraper-blades or fingers b arepreferably secured by means of rivets or otherwise. Said straps are ofsuch proper length that when the shaft is rotated their scraper endswill wind backward and beat against the carcass as it passes near thesame. Suitable mounting brackets 0 having a concave seat portion thatengages the shaft are secured to said shaft by means of boltscv thatpass through the beater-strap. saidbracket and the shaft and clamp thesame firmly'together. As shown, the upper portion of this bracket isprovided with a recess (Z that forms a seat for a portion of a softrubber cushion the inner surface of the beater and said bracket. Thiscushion fits snugly in said recess and is, referably, greater inthickness than the depth of the same so that a space is left between theadjacent end of the bracket and the beater strap, as shown. The upperouter portion of said cushion preferably tapers or reduces in thicknesstoward the strap to a thin edge or lip which bears against the same. Theconstruction of this cushion is such that when the shaft is rotated andthe strap curves backward it causes the cushion to compress and bendwhile the inner portion of the strap will lie against the bracket asshown in'dotted lines in Fig. 2 of the drawings. \Vhen the machine isnot in operation the cushion gives the strap sufficient stiffness tostraighten it out and thus prevents a set forming in the same as thebend or curve is greatest at The cushion may either be separate fromthostrap or may be vulcanized to the same as desired.

In the modification shown in Fig. 3 of the drawings the supportingbracket E is preferably L-shaped having a concave seat 6 near one of itsends whereby it is attached to the shaft F by a bolt 7. The lateral armof said bracket is preferably tangential to the shaft for a portion ofits length and then takes a curve approximately concentric D interposedbetween strap to the axisof the operation and effect of the same isidentical with that described in connection with Figs.

1 and 2 above referred to.

What I claim as new is:-

1. A beater for scraping machines comprising a rotatable shaft, aflexible beaterstrap, a bracket secured to and extending from said shafthaving a portion against which said strap is seated, and a cushionadapted to press against a portion of said strap.

2. A beater for scraping machines comprising a rotatable shaft, aflexible beaterstrap, a bracket secured to and extending from said shafthaving a lateral seat for said strap, and a cushion engaging said seatand adapted to press against a portion of said strap.

3. A beater for scraping machines comprising a-rotatable shaft, aflexible beaterstrap, a from said shaft, a seat thereon for said straphaving a recess in its outer face, and a cushion seated in said recessand engaging said strap.

4:. A beater for scraping machines comprising a rotatable shaft, aflexible beaterstrap, a bracket secured to and extending from saidshaft, a lateral seat thereon for bracket secured to and extending incontact with said said strap having a recess in its outer face, and acushion seated in said recess and engagi said strap.

afi

beater for scrapmg machines com- 4 prising a rotatable shaft, a flexiblebeaterstrap secured thereto, and a cushion adapted to press against aportion of said strap the outer side of said cushion tapering towardsaid strap.

6. A beater for scra prising a rotatable shaft, a flexible beaterstrap,means to which said strap is secured for connecting the same to saidshaft, and a cushion interposed between said strap and said connectingmeans the outer side of said cushion taperin toward said strap.

7. A heater or scraping machines coma rotatable shaft, a beater strap,means to which said strap is secured for connecting the same to sa'shaft having a recess in its outer end, and a cushion seated in saidrecess and engaging said strap, and having an elon ated portion that istapered away from saidrecess in contact with said strap.

8. A beater for scraping machines comprising a bracket secured to saidshaft having an extended ,end provided with a recess, and a cushionseated in said recess and en aging said strap, and having an elongateportion that is tapered away from said recess strap.

In witness whereof]: have hereunto set my hand this 23d day of June1909.
